Description:

Needle Roller Bearing without inner ring RNA NK series

Such bearings without inner ring, suitable for installation dimensions restricted radial supporting structure, and bearing directly as a journal to match rolling surface. As a raceway axis, we must quench the hardware and make grinding, and only be processed to the appropriate size and shape accuracy, the full set of needle roller bearingscan be a higher life expectancy and operation of precision. At the same time, because no inner ring, the diameter of shaft can also be appropriate to increase, thereby also increased rigidity.

Needle roller bearings without inner ring can be widelyused in a wide variety of applications, for example as indexing elements, back-stopping clutches or overrunning clutches. The drawn cup roller clutch fulfils the overrunning or holding function as appropriate.
